Pl PE-RACK.

SPECIFICATION forming part of Letters latent No. 419,112, dated January '7, 1890.

Application filed October 31, 1888- Serial No. 289,623. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. C011, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain newand usefulImprovements in Pipe-Racks, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The object of this invention is to provide an improved form of pipe-rack adapted to support steam or other pipes in proper and relative positions.

The invention consists of a rack made as hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my rack, showing in transverse section pipes supported thereby. Fig. 2 is a face elevation of the same rack. Fig. 3 is a transverse section through one of the rack-arms on line 00 x of Fig. 1.

The first two figures each illustrate the invention by a mere transverse section of a rack, such section being taken out from any portion of the usual length rack, it being understood that the invention may be applied to a rack having any numb r of arms from one upward.

The body A of the rack is formed of any suitable sheet metal, having pipe-supporting arms B, formed in single piece therewith at suitable intervals throughout its length, said arms corresponding and commensurate with the openings a, formed adjacent and opposite to the same, respectively, in the rack-body. The said rack-body curves rearwardly from the baseline of any one arm B at an angle of about forty-five degrees for a distance of about one-third of the total length of surface between the base-lines of two consecutive arms B, such curved portion being the two sections a, formed in the rack-body on opposite sides of the opening a, adjacent to the lower portion thereof. The rack-body curves forwardly from the upper termini of said sections a at an angle of about twenty-five degrees for the remaining two-thirds of the total length of surface between the base-lines of two consecutive openings a, such curved portion being the two sections 04 formed in the rack-body on opposite sides of the opening (1. adjacent to the upper two-thirds portion, more or less, thereof. These curved sections accomplish a twofold result. They form a bed or recess in which the pipe may fit and projecting upper section I), such forward pro-- jection in the formation ofthe arm being adapted to permit of the steam-pipe being inclosed between the latter and the rack-body. The arm is widest at its base, and gradually narrows toward its free upper end. It is formed with a longitudinal central rib 19 projecting for about two-thirds of its length from its base upward, such rib projecting from its outer surface, while a corresponding depression b is formed on the inner surface of said portion of the arm. Said rib is widest at its base, where strain falls on the arm, and gradually narrows toward its upper end, where less strength is required for the arm. This strengthening-rib may be struck up by the same operation which punches or cuts out the arm from the rack-body. So, too, the curvilinear sections of the rack-body, and also of the arms, may be formed simultaneously, so that the entire formation of the complete rack may be accomplished at a single operation by suitable mechanism. A strong, durable, and inexpensive pipe-rack is thus produced.

I claim- 1. A pipe-rack having arms in same piece with the body thereof, said body having rearward and forward projecting formations between the bases of any two consecutive arms, substantially as set forth.

2. A piperack having arms in same metallic sheet piece with the body thereof, said body having openings commensurate with said arms, and also having rearward and for- Ward curved seetionson opposite sides of sueh In testimony that I claim the foregoing to openings between the base-lines of two conbe my inveqtibn I have hereunto set my hand 10 secutive openings, substantially as set forth. this 26th day of October, A. D. 1888.

3. A pipe-rack consisting of body A, having 5 forward and rearward curved sections a and CHARLES 001T a arms B, having sections b and b, and also Witnesses: M having ribs 5 and depressions 12 all in single THOS. B. HALL,

metallic sheet-piece, substantially as setforth. J. B. FAY.
